135-8858: 170mm Outer Diameter Parking Brake Piston Seal

A Parking Brake Piston Seal is designed to maintain the hydraulic pressure and prevent fluid leakage in the Parking Brake unit. When the Parking Brake is engaged, hydraulic pressure is applied to the Piston, which pushes against the Brake Pads, creating friction with the Brake Disc to immobilize the machine. Attributes: • Ensures a secure and leak-free connection • Enhances the Braking Performance Applications: A Parking Brake Piston Seal is used to create a barrier between the Piston and the cylinder bore, preventing fluid from escaping or entering the unit.
